[0033] This utility model provides a height-adjustable speaker. Please refer to [reference needed]. Figures 1-5 The speaker includes a speaker body 1, multiple adjustment brackets 2, and other components that enable structural operation, such as a microphone 12 placed inside the speaker body. Each adjustment bracket 2 is spaced apart on the bottom surface of the speaker body 1. Each adjustment bracket 2 includes a fixing component 4 and a rotating component 3. The fixing component 4 is fixed to the speaker body 1, and the rotating component 3 is rotatably connected to the fixing component 4. The rotating component 3 is used to adjust the angle between itself and the fixing component 4, thereby changing the height of the speaker body 1 to change the sound field and improve the sound quality. Furthermore, by rotating the rotating component 3 on the bottom surface of the speaker body 1, the rotating component 3 can be stored on the bottom surface of the speaker body 1. This design makes it convenient for users to carry, as there is no need for other storage devices to store the rotating component 3; the speaker body 1 can be stored directly, improving the convenience of use.

[0034] In this embodiment, please refer to Figure 2 and Figure 3 The bottom of the speaker body 1 is provided with a receiving groove 11, the fixing component 4 is set in the receiving groove 11, and the rotating component 3 is also stored in the receiving groove 11. That is, when the speaker body 1 needs to be placed directly on the ground or when the speaker body 1 needs to be stored, the user rotates the rotating component 3 so that the angle between the rotating component 3 and the fixing component 4 is 0°, and then the rotating component 3 is stored in the receiving groove 11.

[0035] Furthermore, the fixing component 4 includes a connecting plate, one end of which is a planar structure 41 and the other end is a bushing 42. The planar structure 41 is connected to the bottom of the speaker body 1. In this embodiment, the planar structure 41 is connected to the bottom of the receiving groove 11, and the planar structure 41 is connected to the bottom of the receiving groove 11 by screws.

[0036] In this embodiment, please refer to Figure 3 andFigure 4 The rotating assembly 3 comprises a support column 31, and the end of the support column 31 is rotatably connected with the connecting plate through a rotating shaft 32 penetrating a shaft sleeve 42, wherein the shaft sleeve 42 is internally provided with a buffer 43, the buffer 43 is sleeved outside the support column 31 located in the shaft sleeve 42, and the buffer 43 is mainly arranged to ensure that the rotating assembly 3 is stable at the position after being rotated to a proper angle, and the service life of the rotating assembly 3 is improved.

[0037] As described above, in the embodiment, the buffer 43 comprises a flexible structure such as foam and sponge.

[0038] In order to ensure that the support column 31 is further stable on the ground, the lower end of the support column 31 is provided with a sheath 311, which is arranged to avoid abrasion of the support column 31 and to increase the friction between the support column 31 and the ground. The sheath 311 is detachably connected with the support column 31, so as to facilitate replacement or cleaning of the sheath 311. Specifically, the lower end of the support column 31 is inwardly contracted to form a connecting portion, the sheath 311 is sleeved on the connecting portion, and the outer circumferential side of the sheath 311 is flush with the upper end of the support column 31.

[0039] In the embodiment, the sheath 311 comprises a chamfer 3111 at an angle away from the fixed assembly 4, which is mainly arranged to increase the contact area between the rotating assembly 3 and the ground, so as to enhance the stability of the rotating assembly 3 on the ground.

[0040] In the embodiment, please refer to Figure 1 and Figure 5 The number of the adjusting supports 2 is four, which are divided into a first adjusting support 21, a second adjusting support 22, a third adjusting support 23 and a fourth adjusting support 24. The first adjusting support 21 and the second adjusting support 22 are arranged at one end of the bottom of the sound box body 1, and the third adjusting support 23 and the fourth adjusting support 24 are arranged at the other end of the bottom of the sound box body 1.

[0041] Specifically, please refer to Figure 2 , Figure 4 and Figure 5, the height between the sound box body 1 and the ground can be changed by adjusting the corresponding adjusting support 2, for example, when the sound box body 1 is placed on uneven ground, the angle between the rotating assembly 3 and the corresponding fixed assembly 4 can be adjusted to adapt to the terrain, and for the side of the sound box body 1 placed on the ground, the angle between the rotating assembly 3 and the fixed assembly 4 on the other side can be reduced, thereby increasing the height of the side of the sound box body 1. It should be noted that the maximum angle between the rotating assembly 3 and the fixed assembly 4 is greater than 90°, so the above-mentioned reduction of the angle between the rotating assembly 3 and the fixed assembly 4 on the other side specifically means that the angle between the rotating assembly 3 and the fixed assembly 4 on this side cannot be lower than 90°, and if it is lower than 90°, the height of the side of the sound box body 1 will actually decrease.

[0042] In essence, the height between the sound box body 1 and the ground can be adjusted to the desired preset height by adjusting the corresponding adjusting support 2.

[0043] In another embodiment, the number of adjusting supports 2 is three, the three adjusting supports 2 are arranged at the bottom of the sound box body 1, and the three adjusting supports 2 are arranged in a triangular shape. This design can also adjust the height between the sound box body 1 and the ground, and the operation process is the same as the foregoing, which will not be described in detail here.

[0044] In other embodiments, the number of adjusting supports 2 is five, six, etc. If the size of the adjusting support 2 is large enough, the number of adjusting supports 2 can also be two.

[0045] In some embodiments, please refer to Figure 4 The sound box body 1 is provided with a microphone 12 storage structure for storing the microphone 12. The storage structure can be a cavity for accommodating the microphone 12, and the depth of the cavity is greater than or equal to the length of the microphone 12. The cavity includes an opening, through which the microphone 12 can be vertically or horizontally inserted into the cavity along the length direction to achieve plug-in storage. The microphone 12 fixing structure can be arranged inside or outside the opening to fix the microphone 12 after storage. The opening can be arranged at any position of the sound box body 1, including the top surface, side surface, and bottom surface of the sound box body 1. In addition, the storage structure can also be a groove, and the microphone 12 can be embedded into the groove to achieve plug-in storage. The microphone 12 fixing structure can be arranged inside or outside the groove to fix the microphone 12 after storage. The microphone 12 is vertically or horizontally placed in the groove along the vertical direction of the length to achieve storage. The groove can be arranged at any position of the sound box body 1, including the top surface, side surface, and bottom surface of the sound box body 1.

[0046] In some embodiments, the top of the sound box body 1 is provided with a screen and a storage slot for storing the screen, and a movable structure is arranged between the sound box and the screen, so that the screen can be closed and stored in the storage slot. The microphone 12 storage structure can be arranged below the screen, and after the screen is closed, the microphone 12 is completely covered by the screen and is completely stored in the sound box body 1.

[0047] When the screen is opened, the center of gravity of the sound box body 1 will be offset, and the user will apply pressure to the screen when operating the screen, increasing the risk of the sound box body 1 falling. The adjusting support 2 can increase the contact area of the bottom with the ground, reducing the risk of falling.

[0048] The above is only an optional embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and the attached drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
